Kernel 4.20-rc1 is out

Linus Torvalds announced on 4th November that Kernel 4.20-rc1 is tagged and pushed out, and the merge window is closed. Linux 4.20 brings a lot of prominent changes from AMD Vega 20 support getting squared away, AMD Picasso APU support, Intel 2.5G Ethernet support, the removal of Speck, peer-to-peer PCI memory support, and other new hardware support additions and software features.

Here are some of the features of 4.20-rc 1r:

70% of the patch is driver updates including changes in the gpu drivers

Arch updates in x86, arm64, arm, powerpc, and the new C-SKY architecture),

Updates in the header files, networking, core mm and kernel, and tooling
4. Tooling has been upgraded as well.

The highly anticipated WireGuard secure VPN tunnel is held off until the next cycle. The FreeSync / Adaptive-Sync / HDMI VRR bits are also being held off for DRM until the next cycle.

As the merge window closes, there will be some delay in the pull request which will be taken care of in the second week of the merge window.

The duration of the merge window is two weeks. Linus is considering making an explicit rule that he will stop taking new pull requests some time during the second week unless users have a good reason for why it was delayed.

He also hopes that by the time the next merge window rolls around, there will be a new automation for it, so that everybody just automatically gets notified when their pull request hit mainline.
